non-cyclic photophosphorylation


non-cyclic photophosphorylation
Process by which light energy absorbed by photosystems I and II in chloroplasts is used to generate ATP (and also NADPH). Involves photolysis of water by photosystem II, passage of electrons along the photosynthetic electron transport chain with concomitant phosphorylation of ADP, and reduction of NADP+ using energy derived from photosystem I.
